ABSTRACT
An analysis was made on the incidence of Culicidae present in Playa Municipality, Havana City, during the intensive stage of the anti-aegypti campaign from June to July, 1997, according to its requirements. Culex quinquefasciatus was the predominant species with a total of 269 focuses. It was collected in all the People's Councils and in every type of repository, excepting clay repositories. The second most abundant species was the Aedes aegypti with 199 focuses, followed by Aedes mediovittatus with 67. The Almendares-Sierra, Ampliación-Almendares and Miramar People's Councils showed the highest values of Culicidae infestation in the municipality. The Aedes aegypti prevailed in the first and Cx. quiquefasciatus in the second. The artificial repositories, low tanks and other repositories had the highest number of mosquito focuses in the municipality. The Cx quinquefasciatus preferred the artificial depositories, whereas the A. aegypti preferred the low tanks. Most of the positive depositories were colonized by only one species (92.7 of the total). 7.3 corresponded to mixed focuses. It was found that Cx. quinqufasciatus and A. aegypti were the most associated species.
